Great app to help preserve your phones battery life. You can set an alarm for lower and upper charge limits. I use 30% & 80%. The app also speaks the percentage at your low setting and again when it has charged to (in my case) 80%. When your battery gets to your preset low level it tells you so you know when to charge. Remember to set your phone's app permissions to enable the app to keep abreast of your battery charge level. Nice app which has loads of built in features. I'm impressed. Try it!

Nice application especially when it comes to the widget sizes. Though there are two issues that I think need to be considered: 1. There are times when the application freezes, it does not concord with the actual battery level; 2. Is it possible for the battery widget to look at least almost identical to the image used in it's logo (as it is on Google play for instance)?

Found this app very good. Easy to use and tells me when the battery is either too low or fully charged

Support is excellent. UI is a tad cluttered. Maybe needs UI degrees of user app experience?

The graph allows me to get a clue about how fast the phone is charging or discharging, and *when* that rate changed. Much better time resolution than the built-in Battery app. Also it's nice to be able to check the charge state by pulling down the notifications.

It works great always notifies me when my phone is fully charged and we're it's at capacity wise and the choices of the change of color are very useful and easy to see in the dark while it is changing but chargeing app I could find ever who ever reads this message you should definitely download it I guarantee you won't regret it ps. Thanks for listening to my praise and commentary good luck

Nice app that tells you all you need to know - and a lot you didn't know you needed to know. I especially liked the audible prompts that informs you if the battery needs charging/is charged. One of the best apps in its class.

A must have to protect the life of the battery. In addition takes up very little space. (Works well with other apps.) (Of all the apps. I've downloaded from Google Play Store not one has had any virus, malware, or spyware.)

Gives better quality and clarity hence there is less chance of me having a dead phone. Many thanks. I would tell you more but that option is not working. My comments would have been to say that the main screen looks messy with the adverts and other things which I am sure could be made much more elegant.

It's okay. I use it for the added features rather than it's monitoring ability, which seems to be off by 50% (@93%, system says I have 10 hours and 7 min, the app says I have 21 hours and 37 minutes, even after calibration.) But the widget looks nice and I like the visual and audible alerts that announce the different battery levels. Just discount the monitoring estimates by 50%.

Update: June 30, 2020 The Muzak has stopped. Unfortunately the app generates a popup screen every time the charging cord is connected or even bumped. Happens even with notifications disabled. No app settings to stop this either. Original: Playing constant Muzak (piped music) in the ear piece of the smartphone even on phone calls. No apparent setting to stop this. Only way to end the playing of this audio was by force stopping the app! Likely ad related... Horrible!

Have this on my Samsung a71 5G running Android 11. I have this app set to never be put to sleep, to pull as much power as it needs and never be optimized, it's still disappears from my notification tray. I had it installed for about a year and it happens constantly. Edit: In your reply to this review you told me to email you about the problem. I have done so MULTIPLE times. EVERY reply back is that you're working on the issue. It still HASN'T gotten fixed even though you've updated the app.

Note 2 self: Confusing UI and statistics. Calibrating the phone need to be online, what's the real purpose for that? There is a bug where it always stop while calibrating video, saying it pause to long. It also turns my brightness all the way up. All I want is to see which apps used my battery that can't be detect by the phone battery usage. If I want to see my battery health, Accubattery is still the best, it show easy to understand statistic charts. Uninstalling.

A nicely laid-out app with lots of features. Seems lite on resources. I like the real-time historical graph with selectable parameters. A real nice app. One pro-active suggestion. PLEASE, in future updates, DON'T give in to the temptation to radically change the interface. People HATE that because of the frustration in having to re-learn how to navigate around an app that you comfortably had down-pat. Everyone appreciates a fresh look, but rearranging everything is aggravating. Less is more!

Update: (See original post below) Now the notifications don't work very well. The voice speaks very fast like it is set to 4x. The alarms will Not stop ringing. Stopping the app did not work. I had to completely shut down the phone. Original post: Simple to use. You can set warnings at various battery levels. Is there a way to make it start automatically?

This app now works perfectly. I'm happy. It gives an audio and verbal alert to stop charging, besides a screen pop up. It tracks battery charge on my screen. I do not need to touch anything. At first I had problems, that was my phone...on button stuck off. Rep used hair dryer. Several times.----. Alarm wouldn't turn off. I tried everything, except throwing it. Took to store again. Ring tone on alarms turned off on their own. Google Assistant trying to get into my settings to control everything.

The path to the app via the notification drop-down is easy, the graphs against time give a clear view of what's been going on charge-wise and temperature-wise (tho the graph labels seem to have gone a bit dim either in the last version or since I switched phones), and the easy link to the built-in power-usage breakdown is a welcome convenience. It keeps asking for reviews tho. Once again, "please review me!" Kind of pathetic. Still asking for another review today.
